Available in nine colors, Barefoot Innovations' new GizmoCase is also sold in several variations. The plain GizmoCase -- a rubber iPhone 3G/3GS-holding case -- sells for $17, with no frills. Barefoot also sells bundles of the GizmoCase with add-ons: one bundle is called GizmoCase with Bottle Opener ($30), and includes a lanyard, a back accessory attachment harness and a plastic bottle opener for use with twist-style bottle caps -- the first (and quite possibly last) such accessory we've seen for the iPhone. Another is called GizmoCase with Multi-Purpose Clip ($30), bundled with the lanyard, the harness, and an accessory designed to hold business or ID cards on the back of your iPhone. A holster for belt, purse, or bag attachment is sold separately for $5. No screen protector is offered with any of the bundles, which pretty significantly bulk up the iPhone 3G/3GS with rubber and hard plastic surfaces.

Editors' Note: iLounge only reviews products in "final" form, but many companies now change their offerings - sometimes several times - after our reviews have been published.
This iLounge article provides more information on this practice, known as revving.
